This is a simple sized insert for the 12.6c Food storage container from Target that s popular for storing Pokemon ETBs. When using this insert you would be able to display/store your ETBs without concern for damaging corners. This is sized to fit in the lid. Uploaded this way so that support and printing preferences are up to the printer. Personally I do 3 bottom layers, 2 walls,  and 0% infill at draft height.  This allows for a desiccant pack or 2 if wanted, and cuts down on filament. However, dealers choice.
